Which statement describes the sudden worsening of hyperthyroidism symptoms that may occur with infections or stress?

Choice A rationale

Hyperkalemia, or high levels of potassium in the blood, is not a clinical manifestation of Cushing syndrome.

Choice B rationale

Thin skin that bruises easily is indeed a common symptom of Cushing syndrome. The condition causes the skin to become thin and fragile, leading to easy bruising.

Choice C rationale

A round, “moon face” appearance is another common symptom of Cushing syndrome. This is caused by the redistribution of fat to certain areas of the body, including the face.

Choice D rationale

Weight loss is not typically associated with Cushing syndrome. In fact, weight gain, particularly in the trunk of the body, is a more common symptom.

Choice E rationale

A fatty pad between the shoulders, often referred to as a “buffalo hump,” is a common symptom of Cushing syndrome. This is also due to the redistribution of fat in the body.

Choice C rationale

Insulin plays a crucial role in decreasing blood glucose levels by facilitating the movement of glucose into cells, thereby reducing blood glucose concentrations (nih.gov, n.d.).

Choice A rationale

Glucocorticoids, such as cortisol, generally increase blood glucose levels by promoting gluconeogenesis (nih.gov, n.d.).

Choice B rationale

Glucagon acts to increase blood glucose levels by stimulating the liver to release stored glucose (nih.gov, n.d.).

Choice D rationale

Calcitonin is involved in calcium regulation and has no direct effect on blood glucose levels (Healthline, 2022).
